Hi Patrick-

I have a rather general question about the use of the
"applyToRangeValues(function,data)" Jython method.
What is meant by the function argument? What should it look like? Can
anyone give an example? Thanks a lot.
The function argument is the name of the function that you
want to apply to each timestep in the field. An example
might be:
def changeRange(d):
return applyToRangeValues('testApplyToRange2',d);
def testApplyToRange(d,**args):
r = d.getFloats(0)
total = 0
for i in xrange(len(r[0])):
total= total+r[0][i]
avg = total/len(r[0])
for i in xrange(len(r[0])):
if(r[0][i]<avg):
r[0][i] = 0;
d.setSamples(r)
return d
This avoids having to have the code like:
if (GridUtil.isTimeSequence(newData)):
for t in range(newData.getDomainSet().getLength()):
rangeValue = newData.getSample(t)
XXX do something
newData.setSample(t,result,0)
else:
rangeValue = newData
XXX do something
when you might have a time sequence or just a single timestep.
